Once a facing operation is complete, center drilling frequently follows.Center drilling is performed for two main reasons.One is to create 60 degree bearing surfaces for lathe centers.The other is to create a starting point that will prevent a twist drill from walking offcenter when it begins to cut.Center drills ( combination drill and countersink ) arw usaually held in drill chucks mounted in the lathe tailstock.The tailstock is positioned withthe center drill close to the work piece.It is the feed into the work using the tailstockhand wheel.The small pilots of center drills are fragile, so apply adequate cutting fluid, use ligjt feed, and peck ( retract frequently ) to remove chips from the hole prevent hreakage.

Setelah operasi yang dihadapi selesai, pengeboran pusat sering mengikuti. Pengeboran pusat dilakukan karena dua alasan utama. Salah satunya adalah membuat permukaan bantalan 60 derajat untuk pusat bubur. Yang lainnya adalah membuat titik awal yang akan mencegah putaran putar dari badan berjalan. ketika mulai memotong. Latihan bor (kombinasi bor dan countersink) yang biasanya dilakukan di bor bor dipasang di tailstock tail. Tailstock diposisikan dengan bor tengah dekat dengan potongan kerja. Ini adalah umpan ke pekerjaan menggunakan roda tailstockhand. Pilot kecil latihan tengah sangat rapuh, jadi aplikasikan cairan pemotong yang cukup, gunakan umpan ligjt, dan peck (sering turunkan) untuk menghilangkan keripik dari lubang yang mencegah hreakage.
